At my organization (A fairly large place with tens of thousands of staff) they are looking at curtailing building projects and encouraging more flexible working where staff come in to an office (note, not "their" office but "an" office) a couple of times a week with the rest spent working from home.
Many of the staff I've spoken to have supported this. A lot of people miss the real-life interaction with their colleagues so welcome being able to see people in real-time but don't want the five-day-a-week commute. There are a few grey-bears who are clinging to the idea that in X weeks time everything will be back to normal (i.e. Pre March 2020) But I think they are the minority.
